I’m wondering if Flyer ever produced a version of the 944 Brownhoist that actually had 6 wheels in the truck. The reason I ask is that I noted that the side trucks are bored for 6 wheelsets, but mine only came with 4 wheels.
Since I routinely upgrade all my rolling stock to metal wheelsets anyway, I took two of the old plastic wheels chucked them up in my drill and ground off the flanges. Here they are reinstalled with the new wheels.
